- Previous studies suggested that blood donors may have lower mortality risks, potentially due to the "healthy donor effect," which can lead to selection bias if not properly controlled.
- This study analyzed data from the Sax Institute's 45 and Up Study to compare regular high-frequency blood donors (donating at least twice a year) with low-frequency donors over a 7-year period, using advanced statistical methods to reduce confounding factors.
- Results showed no significant difference in mortality between regular high-frequency and low-frequency donors, indicating that frequent blood donation does not correlate with lower all-cause mortality when bias is minimized.
Objective: Adverse birth outcomes and the maternal severity of influenza in pregnancy are well documented but information on pertussis is limited.
Design: Population-based linkage data were collected during 2001-2016.
Setting: New South Wales, Australia.
Background And Objectives: Crash injury risk is reduced when a child correctly uses an appropriate restraint; however, incorrect restraint use remains widespread. The aim of this study was to determine whether product information developed using a user-driven approach increases correct child restraint use.
Methods: We conducted a two-arm double-blinded parallel randomised controlled trial in New South Wales, Australia 2019-2021.
